E-Class Sedan

All-round safety, outstanding comfort and fuel savings of up to 23 percent

The new E-Class from Mercedes-Benz represents the pacemaker when it comes to safety, comfort and environmental compatibility in this market segment. With its unique combination of driver assistance systems, this saloon further consolidates the leading position of Mercedes-Benz in the luxury class. Its features include a drowsiness detection system, Adaptive Highbeam Assist and the proximity control system which is capable of performing automatic emergency braking when there is acute danger of a collision.

Mercedes-Benz has improved the already exemplary long-distance comfort of the E-Class even further in the new saloon, principally through the use of intelligent bodyshell technology with up to 30 percent greater rigidity, further improved seats and a newly developed suspension whose shock absorbers automatically adjust to the current driving situation. The optional air suspension now works in combination with an electronic damping system.

The outstanding safety and comfort of the E-Class are matched by its environ-mental compatibility and economy: the four- and six-cylinder engines are direct-injection units, and consume up to 23 percent less fuel than before. The combined NEDC consumption of the new four-cylinder CDI engines is just 5.3 l/100 km (44.38 mpg/US, 18.86 km/l),which corresponds to 39 grams of CO2 per kilometre. All the engines for the new E-Class meet the EU5 emission standard, while the emissions from the E 350 BlueTEC are already below the EU6 limits planned for 2014.

Along with the engines, the BlueEFFICIENCY package for the E-Class is in large part responsible for the considerable fuel savings. Engineers from every development department have worked together to optimise assemblies and components, to save fuel by means of reduced weight, a new form, improved functioning or efficient energy management.

The work done in the wind tunnel was particularly successful, as the resulting drag coefficient of only 0.25 makes the new E-Class the world’s most aero-dynamically efficient luxury saloon. It betters the already good Cd figure of the preceding model by another four percent, which represents a fuel saving of around 0.25 l/100 km when driving at a motorway speed of 130 km/h (80 mph). One of the measures taken to improve the aerodynamics is the adoption of automatically adjustable fan louvres which control the airflow to the engine compartment in line with the engine’s cooling requirements.

Fuel consumption display

Other BlueEFFICIENCY measures include newly developed tyres with up to 17 percent lower rolling resistance, energy-saving control of the alternator, fuel pump, air conditioning compressor and power steering, and the ECO start/stop function which switches the engine of the new E 200 CGI off when idling. Displays in the speedometer inform the driver how much fuel is being consumed (liters per 100 kilometres), and when the next higher gear should be selected in order to maintain an economical and environmentally conscious style of driving.

The range of engines available for the new E-Class comprises four, six and eight-cylinder units with outputs from 100 kW/136 hp to 386 kW/525 hp. The four-cylinder engines are newly developed direct-injection units, which develop a higher output and torque than the comparable V6-engines of the preceding series despite a smaller displacement. The strategy is to replace large, naturally aspirated engines with turbocharged units which excel with advantages such as lower weight, reduced internal friction and more economical operating characteristics.

With three completely newly developed four-cylinder engines, the E-Class also remains one generation ahead where diesel technology is concerned. These engines feature latest-generation common-rail direct injection, fast piezo injectors, improved exhaust gas recirculation and an innovative twin turbocharger, making for fast responsiveness and good performance characteristics. These qualities are reflected in the figures: the E 250 CDI with 150 kW/204 hp and 500 Nm (368 lb-ft) develops a 25 percent higher torque than the previous V6 diesel engine, but uses around 23 percent less fuel at only 5.3 l/100 km (44.38 mpg/US, 18.86 km/l) NEDC (New European Driving Cycle). This corresponds to 139 grams of CO2 per kilometre.

E 350 CDI ELEGANCE

The new four-cylinder diesel engine also powers the E 200 CDI BlueEFFICIENCY with 100 kW/136 hp and the E 220 CDI BlueEFFICIENCY with 125 kW/170 hp, also with a fuel consumption of 5.3 l/100 km, (44.38 mpg/US, 18.86 km/l).

E 350 4MATIC

The top model in the new E-Class diesel range is the six-cylinder E 350 CDI BlueEFFICIENCY with an output of 170 kW/231 hp, which uses 0.5 litres less fuel per 100 kilometres than the previous E 320 CDI. From autumn 2009 the V6 diesel will also be available as a BlueTEC model with the world’s best emission control technology. The E 350 BlueTEC develops 155 kW/211 hp and meets the EU6 exhaust emission standards planned for 2014. All the other engine variants in the new E-Class meet the EU5 limits.

Petrol engines: 20 percent fuel saving thanks to direct injection

Mercedes-Benz equips the BlueEFFICIENCY models E 200 CGI and E 250 CGI with the newly developed four-cylinder direct petrol injection engine with a displacement of 1.8 litres, turbocharging and variable intake and exhaust camshafts. The E 200 CGI BlueEFFICIENCY (135 kW/184 hp) is equipped with a six-speed manual transmission and the ECO start/stop function as standard, and consumes only 6.8 l/100 km(34.59 mpg/US, 14.70 km/l) of premium petrol (combined NEDC), . This equates to 159 grams of CO2 per kilometre.

In the E 250 CGI BlueEFFICIENCY (150 kW/204 hp), which has a five-speed automatic transmission as standard, maximum torque is now 310 Nm (229 lb-ft), which represents an increase of more than 26 percent over the previous V6‑engine. At the same time the NEDC fuel consumption is reduced by over 20 percent to 7.3 l/100 km, (32.22 mpg/US, 13.69 km/l) equating to 174 grams of CO2per kilometre.

E 500 BlueEFFICIENCY

As before, the E 350 CGI BlueEFFICIENCY with direct petrol injection (215 kW/292 hp) and the top-of-the-line E 500 (285 kW/388 hp) are included in the range of engine variants in the new E-Class. By optimising details of their design, it has been possible to reduce the fuel consumption of these V6/V8 models by up to 0.6 litres per 100 kilometres. For the ultimate in performance, the E 63 AMG from Mercedes-AMG develops 386 kW/525 hp.

Engine of the E 350 CGI BlueEFFICIENCY

Mercedes-Benz equips the V6 and V8-models as standard with a seven-speed automatic transmission, steering wheel selector lever and shift paddles.

Customers can also choose to combine the E 350 CDI BlueEFFICIENCY and the E 350 V6 models, as well as the eight-cylinder E 500, with the latest-generation Mercedes all-wheel drive which is more efficient, lighter and more compact than the previous all-wheel drive technology. These advantages produce noticeably better traction and fuel savings.
